My present invention has reference to a new and novel construction ofshoes, and my object is the provision of a shoe having an insole orinner sole construction of such character as to afford elasticity to thefoot of the wearer and likewise force continuous blasts of air againstthe wearers foot as long as he is walking.

To the attainment of the foregoing the invention consists in theimprovement hereinafter described and definitely claimed.

In the drawing:

Figure 1 is a side elevation of the improvement, with parts in sectionof a shoe constructed in accordance with this invention.

Figure 2 is a plan view of the inner sole.

Figure 3 is aplan view of the main sole with the inner sole or liningremoved.

Figure l is a detailed perspective view looking toward the rear of themetal heel plate.

The shoe is indicated in the drawing by the numeral 1, the main sole bythe numeral 2 and the heel by the numeral 3. The outer edges of the mainsole 2 have stitched on the edges and ends thereof a continuous leatherstrip 4. Thus the main sole 2 has its top formed with a depression whichafiords an air chamber or pocket. The upper of the shoe is stitched tothe leather strip or flange 4: and received in the air pocket in themain sole 2 and secured therein in any desired or preferred manner thereis a leather sheet or strip 5. The portion of this sheet extendingbeyond the arch of the shoe and over the sole proper is centrallyslitted or divided to receive therein a thin metal plate 6. By slittingthe sheet, at the sole portion thereof, and arranging the metal plate 6therein the coiled expansion springs (hereinafter to be described) Willembed themselves in the upper slitted portion of the i sheet 5 and willthereby be held properly positioned.

The insole 8 rests on the flange 4 and is stitched thereto, as at 8. ofleather and as disclosed by the drawing has both its body or soleportion as well as its heel portion provided with series of bothlongitudinally and transversely arranged apertures 9 that afford airpassages. For distinction the sole portion of the inner sole isindicated by the numeral 10, the arch by The inner sole is Serial No.556,671.

said springs bear against the upper face of the split sole portion ofthe leather member 5, and exerting pressure against'the metalreinforcing plate therein. This, as previously stated, will hold thesprings 15 properl positioned. The inner end of the plate 13 hascentrally fixed thereto by rivets or'like elements an arched metal shank15 which is arranged beneath the arch 11 of the insole 8.

The metal shank 15 is arched so that the v same will overlie and haveits free end connected to a thin metal plate 16 which is arranged overthe heel portion of the leather member 5. The heel portion 12 of theinsole has secured on its inner face a metal .7

plate 17 which is provided with apertures that register with theapertures in the said heell portion of the shoe. The plate is, ofcourse, shaped to correspond in shape to the heel portion 12 of theinsole and likewise, the heel portion of the main sole of the shoe. T heplate 17 has fixedly secured on its inner face a plurality of shorthelical springs 18 which are in contact with the metal plate 16. Theouter rounded edge of the notchesQO to aiford air ports or passages, andthe rounded edge of the heel portion 12 of the insole is notched toprovide the same with plate 17 is provided with a flange 19 that hasspaced an arcuate slot 21 disposed opposite certain of the notches 20 ofthe flange 19. The notches 20, and 21 afford air passages for the rearofthe shoe 1.

The plate 17, and the plate 13 are of thin but strong metal while theshank plate 16 is of stiff metal. The flanges 19 (which are of a lesslength than the normally expanded springs 18), when brought'against theplate 16, by the weight of the user of the shoe, limits the compressionof the springs 18, and

consequently the movement ofthe, heel plate 17 in the direction of theheel of the shoe. The sole and shank portion of the insole 8 has itsedges stitched to the flange 4 of the main shoe and to the inturnededges of the body of the shoe, so that only the central and reinforcedportion of the sole part 8 of the insole is yieldable.

From the foregoing description. when read in connection with theaccompanying drawing it will be apparent that the improvementeffectively cushions the foot of the user of the shoe and that inwalking the yieldable sole and heel portions of the inner sole willbedepressed when the shoe is brought into ground contacting position andwill be expanded when the shoe is lifted off the ground so that the footof the user is afforded a, con,- tinuous circulation of air. Theimprovement is, broadly speaking, in the nature of an air pump and suchair is not only distributed to the sole and under face of the heel ofthe user, but along the sides of the users foot and especially along thesides of the heel of the user of the shoe. The foot of the user isnaturally moved toward the front of the shoe and is not in directcontact with the rear of the shoe, so that the ports or notches 20 and21 will open to each other and a vol.- ume of air will be pumped throughthese notches. When, however, the foot of the useris set for action, orin other words the user is walking, the foot in the shoe slides towardthe back of the shoe, commonly called the counters, and such movementwill cover the notch 21 so that an intermittent flow of air is directedthrough the said notch or open.- ing 21 when the user raises and lowershis foot in ground contacting engagement when walking. The inner sole isof soft leather and effectively cushions the foot of the user of theshoe and it is thought the foregoing derounded rear portion providedwith a depending flange which is notched, coiled compression springs onthe under face of the said apertured plate of a normal length greaterthan that of the flange, and a leather inner sole having its front andrear portion apertured, its central portion connected to the metalshank, its edges stitched to the flange of the shoulder and the roundededge of its heel portion provided with an arcuate notch disposedoutwardly of the notched flanges on the apertured heel plate.

In testimony whereof I aflix my signature.

scription will fully and clearly set forth the I simplicity of myconstruction and the advantages thereof, so that further detaileddescription will not be required.

It is to be further noted that the improve ment provides the shoe with adouble air pump, one arranged at the sole andthe other at the heelportion of the shoe.

Having described the invention, I claim;

A foot cushioning and ventilating shoe including a sole provided with acontinuous upstanding flange that affords the sole with an air pocket, acompressible strip arranged in the pocket and having its sole-portioncentrally slitted, a metal reinforcing plate in the slit, a thin metalplate overlying; the strip at the heel portion thereof, a stifli metalshank secured to the arch ofthe strip and to the metal heel plate, anapertured metal plate to which the front end of the shank is secured,coiled expansion springs between said apertured metal plate and the soleportion of the compressible strip, an apertured plate at the heelportion of the pocket having its
